write the equation x+2y=12 in slope intercept form and find the slope.

Question

1.The equation of a straight line is given by 3x-8y+24=0, rewrite the equation of the line in slope intercept form.

ii find the x-intercept and y-intercept in coordinate form.

 

2.write the equation x+2y=12 in slope intercept form and find the slope.

Answer 1

3x-8y+24=0

3x+24=8y

8y=3x+24

y=(3/8)x+3

x=0, y=3, (0,3)

y=0, x=-8, (-8,0)

 

x+2y=12

2y=-x+12

y=(-1/2)x+6

slope=(-1/2)
